Greetings Everyone,

I was thinking that there must be a way of getting around the onboard phono stage to convert it to line in. Then I remembered an article I saw a few years ago. I've never tried it, but I'll need to :yes: as I am now really into boomers :-)

I haven't seen the solution that Superduper referred to yet, no doubt this will come in time.....

Here's the link I was referring to. If it's been previously posted, please accept my apologies.

If you are trying to connect an MP3 player to your Phono jacks, you can buy an adaptor like Superduper mentioned. Not many people sell them, but there are a couple companies that do. You can velcro it to the side of your boombox.

I use my boomboxes to listen the radio, cassettes and MP3 player.
There are several options for connecting an MP3 player to the boombox:
1) through FM Transmitter
2) through cassette adapter
3) through the line input
I check 3 MP3 players, volume is on max, but output level is so lower.
In electronics sites found assembled preamplifier with TL 082.
The gain is determined by the value of the resistor in the feedback.
The picture shows how to connect:

I decided to embed this preamplifier in one of my boomboxes.
I found a place to mount the board.
When I finished, it's time to tests.
The level indicators show +3db.
MP3 player volume is on 40%, equalizer is off or flat.
Now, the sound is good!!!

hiii there i had similar problems and bought myself a passiv line/phono converter..

http://www.amazon.de/gp/product/B002J4L ... 02_s00_i01

this one .. quit cheap and im using quit a strange wire setup.. most of my boxes have only a din input so im using a din/rsa cable... for tqo boomboxes together on an mp3 player im using a rsa/ 2x rsa plug ..
well and because my aiwa 660 can handle the mp3 signal directly and my aiwa 950 reacts super sensitiv im using the line/phono converter only for the aiwa950 and direct input for the aiwa660.. and if i wanna use my pana 5500 i use anothe rsa/ 2x ras plug.. ;)) looks like **** but works ;))

i was thinking about using a car fm-modulator transmitter but they sound like crap...

best sound is pure radio ;)
